ENZYM ACTIVATION
Activating NAD⁺-related enzymes through exercise is one of the most natural and effective ways to support cellular health and longevity. Here's how it works and what you can do:
The Science: How Exercise Activates NAD⁺-Related Enzymes
Exercise stimulates a demand for energy in cells, especially in muscles. This increases the activity of mitochondria, which in turn elevates the NAD⁺/NADH ratio — a key signal that triggers the activation of NAD⁺-dependent enzymes, including:
1. Sirtuins (especially SIRT1 and SIRT3)
- These enzymes help regulate inflammation, DNA repair, fat metabolism, and longevity.
- Their activation depends on NAD⁺ availability.
2. AMPK (AMP-activated protein kinase)
- Exercise activates AMPK, which boosts NAD⁺ biosynthesis by upregulating the enzyme NAMPT, a key step in the NAD⁺ salvage pathway.
3. PGC-1α (Peroxisome proliferator-activated receptor gamma coactivator 1-alpha)
- Promotes mitochondrial biogenesis, partly through sirtuin activation.
Best Types of Exercise to Boost NAD⁺ and Activate Enzymes

Tip: Aim for at least 150 minutes of moderate or 75 minutes of vigorous activity per week for general metabolic benefits.
Supportive Lifestyle Factors
- Intermittent Fasting: Elevates NAD⁺ levels and activates sirtuins
- Cold Exposure (e.g., cold showers): Can increase mitochondrial activity
- Sleep and Recovery: NAD⁺ and sirtuin activity are regulated by circadian rhythms
Summary: How to Activate NAD⁺ Enzymes with Sport
- Exercise regularly, focusing on endurance and high-intensity training
- Train in a fasted state occasionally to boost NAD⁺/NADH ratio
- Support recovery with sleep, nutrition, and hydration
- Combine with healthy stressors (like fasting or cold) to enhance results
- Consider supplementing NAD⁺ precursors (e.g. NMN or NR) if needed
